Localization of tricholeukocytes in variant hairy cell leukemia on a light scatter diagram and morphology of hairy cells in a blood smear.

When performing flow cytometry (leukocyte distribution diagram), in which cell area are tricholeukocytes identified?

1 — lymphocytes 2 — monocytes 3 — neutrophils 4 — eosinophils

Figure 1. Variant HCL: 9000 leukocytes per cubic millimeter, 33% hairy lymphocytes. Figure 2. Leukocyte distribution diagram in this case.
